Surface construction based on a laser scanning adult penis 3D data model / 中华医学美学美容杂志

ABSTRACT

Objective:To construct a surface model of penis and adjacent structures with clear anatomical features by using the three-dimensional laser scanning technology and to explore the application value in the three-dimensional reconstruction of adult penis soft tissue.Methods:Sixty cases of healthy male subjects (25 to 28 years old) were chosen from January to December 2019 from Inner Mongolia region in Inner Mongolia Medical University Hospital; subjects were divided into 3D digital model measurement and manual measurement groups, each 30 cases. 3D digital model group was measured with 3D laser scanning for adult penis and adjacent to the structure of three-dimensional digital model of the related software on the penis morphological measurement. The results of the manual measurement group was compared with those of the 3D digital model group.Results:The model obtained by 3D laser scanning could rotate and scale smoothly, observe the penis and adjacent structure from any angle, conduct simulation operation, and complete measurement quickly and accurately, with no significant difference between the 3D digital model and manual measurement results.Conclusions:3D laser scanning technology is a simple, accurate and efficient method for soft tissue reconstruction and non-contact measurement of adult penis. The measurement results are completely reliable, and the measurement error conforms to the requirements of anthropometry, providing an important morphological data source for clinical penile plastic surgery.
